Clean energy firm takes $9.5M Series B

Sun Catalytix Corp., a Cambridge, Mass.-based clean energy startup, said Thursday it has received $9.5 million in a Series B funding round.

The energy storage and renewable fuels firm said the round was led by Tata Limited and included participation from Polaris Venture Partners and other investors, which weren’t disclosed.

Sun Catalytix said the funding would support continued development of the company’s technology, which aims to enable the conversion of electrical, solar or wind energy to storable energy at “transformative” cost targets.

The technology uses catalysts that split water and generate hydrogen and oxygen from water - producing renewable electricity in “benign and simple operating conditions,” according to the company.

Sun Catalytix spun out of the Massachusetts Institute of Technology to commercialize water-splitting research from the labs of Daniel Nocera, an MIT chemistry professor.

The company received a $4.1 million award last November from the U.S. Department of Energy’s Advanced Research Projects Agency – Energy (ARPA-E). That same month, the company received a third round of seed funding from Polaris, worth $1 million.
